The FPS Calculator tells you roughly what FPS you can expect in a specific game, on a specific GPU and CPU, at a specific resolution and settings level — using real benchmark data.
1. Pick your game. Only games we've actually tested show results.
2. Pick your GPU and CPU. These are the two pieces of hardware that matter most for FPS.
3. Pick your resolution (1080p, 1440p, or 4K) and settings (Low, Medium, High, Ultra, etc.).
4. Read your result — you'll get an estimated average FPS and a 1% low FPS.
Average FPS is the number most people care about — the typical framerate you'll see.
1% low FPS is how bad your worst moments get. A game can have a great average and still feel choppy if the 1% low is much lower — that gap is usually what people mean when they say a game "feels stuttery" even though the FPS counter looks fine.
Both numbers matter. A high average with a rough 1% low is a worse experience than a slightly lower average that stays consistent.
Every setup is a little different — background apps, drivers, the exact moment in a game you're measuring. These numbers come from real benchmark runs, so the result is shown as a realistic range instead of pretending there's one magic number.
Trying to decide between two GPUs instead of checking one you already have? Use the GPU vs GPU Comparison tool to see them side by side in the same game.
